Subject: [PATCH 21/26] fix: use plain background for gitsigns highlights

Problem: gitsigns groups were linked to DiffAdd/DiffChange/DiffDelete,
which have tinted backgrounds that look out of place in the sign column.

Solution: define GitSignsAdd, GitSignsChange, and GitSignsDelete with
foreground-only highlights so they inherit the normal background.

Subject: [PATCH 23/26] build(flake): add nix devShell

Problem: no nix dev shell existed, making it harder to get local
tooling for formatting, linting, and type checking.

Solution: add a flake with a devShell providing prettier, stylua,
selene, and lua-language-server.
